Abstract: Digital communications place ever-increasing demands on the linearity of power amplifiers. To meet these challenges, the system engineer needs to either increase the maximum output power of the amplifier, if the DC power or thermal limitations allow this, or improve the linearity of the amplifier. We have developed very broadband predistortion linearisers for traveling wave tube amplifiers (TWTA). These predistortion linearisers are based on only two custom MMICs and operate at S,C, Ku, K and Ka frequency bands, thus covering the most important frequency bands currently in use.
